PostgreSQL has three shutdown modes: smart, fast, and immediate. For many years, the default has been "smart", but Bruce Momjian has just committed a patch to change the default to "fast" for PostgreSQL 9.5. In my opinion, this is a good thing; I have complained about the current, and agreed with others complaining about it, many times, at least as far back as December of 2010. Fortunately, we now seem to have now achieved consensus on this change.

Amit Kapila and I have been working very hard to make parallel sequential scan ready to commit to PostgreSQL 9.5. It is not all there yet, but we are making very good progress. I'm very grateful to everyone in the PostgreSQL community who has helped us with review and testing, and I hope that more people will join the effort. Getting a feature of this size and complexity completed is obviously a huge undertaking, and a significant amount of work remains to be done. Not a whole lot of brand-new code remains to be written, I hope, but there are known issues with the existing patches where we need to improve the code, and I'm sure there are also bugs we haven't found yet.
